Ive had 2 stroke in my 300 disco (100ml to 20ish litre diesel) and must admit she runs smoother and does more noticable mpg and i mean more noticable! like 25+ miles per £30! (around 115 miles = roughly 24-25 mpg) and i dont exactly hang around either :lol: would prob get more mpg if i drove her properly!!! with the engine mods i dont think thats bad mpg for a landy of this size,age,weight etc......
